edge 17. Owing to the fact that this plane face of the valve oradjustable weir does not intersect the line about which it is rotatable,a movement of the rod 20 in one direction raises that edge of said valvewhich is adj acent the reservoir 8 and thus requires the accumulation insaid reservoir of a body of lubricant greater than that whichwould Underoperating conditions, the arm 20 is so connected to the arm 2 of theengine throttle valve that whensaid valve is in a posit-ion to cause theengine to operate under normal conditions, the valve or weir 18 is inthe position shown in Fig. 3. Consequently, the operation of the pump 15maintains the lubricant in the reservoir 8 at the level shown and' thesplashing up Ofo said lubricant by the parts 9 of the connecting rodoperating therein, causes a certain part of the oi. from this reservoirto flow into the gutters 10 adjacent thereto so that it passes to thereservoir 7. As long as j the engine is working under normal conditions,the level of lubricant in this reservoir remains at a very definiteheight sufficient to cause roper lubrication of the engine parts and atthe same time the oil splashed up from this reservoir by the'connectingrod is passed by the gutter adjacent thereto to the reservoir 6 and so011. Thus, a predetermined and suitable supply of oil is provided andits level in the reservoir 8 is maintained at a predetermined point,since the surplus supplied by-thepump 15 would be immediately dischargedinto the storage tank 14: over the weir edge 17 and the valve 18. If,now, the throttle valve of the engine be opened in view of an increasedload or in order to obtain an increase of the speed, the valve or wier18 is so turned through the link 21 and the arm 20, as to prevent flowof oil from the reservoir 8 until the amount therein has been increasedto such a height as to permit of it overflowing the raised edge of thesaid valve 18; it being of course understood that the pump 15 is at alltimes operated at a speed necessary to raise the level of lubricant inthis tank in spite of the action of the engine in removing it from thesame.

As a consequence of the increased height "of lubricant in the reservoir8, a larger quan tity of oil is splashed up by the connecting rodoperating therein and this increased amount passes to-the succeedingreservoirseach of which is thus provided with an abnormal amount of oil,so that the engine, as a unit, has in active circulation the greateramount of lubricant required by the increase of load. The oil from thereservoir 5 passes from the trough 11 through the conduit 12 and thepipe 13 back to the storage tank 14-,

The return of the throttle to its normal open position likewise causesthe adjustable wier to be brought back to the position said container;means for supplying oil to the container; with means for varylngtheposition of the bottom edge of theoverflow opening to vary the depth ofoil in the container. e

2. The combination of an oil reservoir having an overflow opening; amember peri odically entering the reservoir for removmg 011 therefrom;means for supplying oil to the reservoir faster than it is removedtherefrom by said member; and means for adjusting the overflow to varythe depth of oil in the reservoir. v i 3. The combination with thethrottle of an engine,- of an oil reservoir; a movable member mounted toenter the reservoir for removing oil therefrom; means for supplying oilto the reservoir; and a device for.

varying the depth of oil in the reservoir operatively connected to thethrottle so as to be adjustable therewith.

4. The combination with the throttle of an engine, ofv an oil reservoirhaving an overflow opening provided with an adjust-- able member forvarying the depth of oil said member with the engine throttle to causeit to be adjusted with said throttle; and means for supplying oil to thereservoir.

5. The combination of an engine crank case having a series of reservoirsformed to be entered respectively by portions of the engine; means fortransmitting to certain reservoirs the oil splashed up from otherreservoirs; a storage reservoir connected to an end one of saidreservoirs; means for delivering oil from the storage reservoir to theother end reservoir; said last reservoir having an overflow openingdischarging into the storage reservoir; and means for adjusting thedepth at which the,

oil in said last reservoirdischarges through said overfiow- 0pening.-
